Q2:

Symmetrical component theory is widely used in power system analysis. Design and develop a program that can be used for solving problems associated with symmetrical components.

• Program 1 allows input of line voltages (V_R, V_Y, V_B) and line currents (I_R, I_Y, I_B) and then computes values of the Zero sequence power (P₀), Positive sequence Power (P₁) and Negative sequence Power (P₂) components using Symmetrical Components Theory.
• Program 2 allows input of symmetrical components i.e. V₀, V₁ and V₂ and I₀, I₁ and I₂ of line currents and then computes values of phase powers i.e. (P_R, P_Y, P_B).
• Test your programs using at least three different values. Tabulate sample results using the program 1 and program 2. Include screen shots of the sample results.

Q3:

Load flow studies are widely used in power system analysis. Design and develop a program that can be used for solving problems associated with load flow analysis.

The proposed Program allows input of number of busbars, voltages, load powers, admittances and estimates voltages at various buses using Gauss-Seidel load flow method.

Test the developed program using A single line diagram of power system network shown in Figure Q3.  Include screen shots of the program and results.

All values are in p.u. and on common base.

Estimate V₂/d₂ using Gauss-Seidel load flow method for 2 iterations.  Start with Initial value V₂⁽⁰⁾ /d₂^o = 1.0/0⁰ p.u, as shown in the diagram
